Solutia chemical foaming agent hydrazine hydrate _ Wei (certified) _ hydrazine hydrate provided by Qingdao Chengyang Wei Connaught Chemical Co. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) is specialized in the "phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol," the business, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Feng Zhongying. Tied with 85% hydrazine hydrate, ethanol, Pd-C catalyst; reflux, then hydrazine hydrate rubber chemicals, must be in strict isolation system under air, this is a bit dangerous. : Cool: general heavy metals like with hydrazine hydrate system a bit dangerous, because for dissolved oxygen in water can cause corrosion of boiler tubes. Hydrazine hydrate was added to the boiler feed water, not only oxygen, but also to prevent the dissolved iron and copper boiler scale formation. Do choose the ideal spacecraft fuel hydrazine hydrate, high calorific value, reacts with oxygen to produce water and nitrogen which is non-polluting substances. Hydrazine Hydrate: generalized antioxidants refers radical scavengers of reactive oxygen species and blocking agents repair agent material collectively [1]. That can only remove free radicals and reactive oxygen species is reducing antioxidants, reducing agents and antioxidants are not peer concept, but not called another name. The reducing agent itself is oxidized to lose electrons oxidation products, such as the reduction reaction of copper oxide with hydrogen, the hydrogen is oxidized into water loses electrons. Reducing performance in reducing the reaction. Reducing power loss of strength is reducing the strength of the electronic capabilities, such as the number of sodium atoms lose electrons less than aluminum electronics, reducing power of sodium atoms stronger than aluminum atoms. Containing substance used as a reducing agent is easy to lose electronic elements, particularly in the analysis of the reaction, common elements valence lift judgment: the valence of the elements contained elevated substance as reducing agent. Application of hydrazine hydrate and prices in the electrode wire, such as elemental Mn, Si hydrazine hydrate carbon dioxide, Al, Ti and Zr, etc., can effectively prevent the infiltration of oxygen and so will not form an oxide in the weld metal in the pores [2].
